Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38418, here are decompositions:
- 41 + 38377 = 38418
- 47 + 38371 = 38418
- 67 + 38351 = 38418
- 89 + 38329 = 38418
- 97 + 38321 = 38418
- 101 + 38317 = 38418
- 131 + 38287 = 38418
- 137 + 38281 = 38418
Showing the first eight; more decompositions exist.
